Again there's NO SKIN in the gut. Your dermal layer or epidermis is the stuff we call skin - it's on the outside. Your gut lining is NOT SKIN. Your skin protects you from, for examples, absorbing moisture (you'd drown in the rain without drinking if it didn't) whereas the gut is designed to absorb moisture etc.
There ARE (it may well be winstrol as Lev says) just one or two steroids which are normally injectable but can be ingested. However, as I said earlier, they are the ONLY ones.
ALL and I mean ALL of the rest (except for the actual orals) were specifically created in labs to be taken as injectables. Heck so was Winstrol. Lev is correct in saying any injectable swallowed will be broken down. Just as orals have to be methylated due to what's called 'first pass 'issues' injectables were designed to be used intramuscularly for a reason.
And just because you can doesn't mean you should. This is a bang for the buck issue. You'll get more from jabbing that swallowing.
